Description
Die vorliegende Erfindung betrifft geneigte Schraubenfedern im Allgemeinen und betrifft insbesondere geneigte Schraubenfedern verschiedener Ausführungen.The The present invention relates to inclined coil springs in general and particularly relates to inclined coil springs of various designs.
Eine allgemeine Erörterung dieser Arten geneigter Federn des ringförmig geschlossenen Typs und die konstruktive Weiterentwicklung von Federn ist in den U.S.-Patenten Nr. 4,655,462; 4,826,144; 4,830,344; 4,893,795; 4,876,781; 4,907,788; 4,915,366; 4,961,253; 4,974,821; 4,964,204; 5,160,122; 5,108,078; 5,139,276; 5,203,849; 5,239,737; 5,503,375; 5,615,870; 5,709,371; 5,791,638 nach Balsells dargelegt.A general discussion of these kinds of inclined springs of the annularly closed type and The constructive evolution of springs is disclosed in the U.S. Patents No. 4,655,462; 4,826,144; 4,830,344; 4,893,795; 4,876,781; 4,907,788; 4,915,366; 4,961,253; 4,974,821; 4,964,204; 5,160,122; 5,108,078; 5,139,276; 5,203,849; 5,239,737; 5,503,375; 5,615,870; 5,709,371; 5,791,638 according to Balsells.
Die Kraft-Federwegs-Eigenschaften bislang verfügbarer Axialfedern des ringförmig geschlossenen Typs wurden durch die Änderung zahlreicher Federparameter variiert, einschließlich der Größe des Drahtes, der Höhe der Wicklung, des Abstands der Wicklung und der vorderen und hinteren Anschlagswinkel. Während man mit diesen Parametern die Last-Federwegs-Eigenschaften der Feder gezielt „zuschneidern" kann, sind sie weder der beherrschende Faktor noch kann so das gesamte Konstruktionspotential der Feder ausgeschöpft werden.The Force-travel characteristics of previously available axial springs of the annular closed Type were replaced by the change varied spring parameters, including the size of the wire, the height the winding, the distance of the winding and the front and rear Squares. While one with these parameters the load-spring characteristics of the spring they are neither "tailored", they are neither the dominant factor still may be the entire design potential the spring exhausted become.
Ein bislang verkannter Parameter, der sich nachhaltig auf den Wirkungsgrad axial belasteter Federn des ringförmig geschlossenen Typs auswirkt, ist in den U.S.-Patenten Nr. 4,826,144 und 4,915,366 dargestellt. Diese Druckschriften offenbaren Wicklungen, die in einer Weise miteinander verbunden sind, dass sie eine flexible Schraubenfeder des ringförmig geschlossenen Typs bilden, wobei sich der hintere Anteil entlang eines Außendurchmessers der axial flexiblen Schraubenfeder des ringförmig geschlossenen Typs und der vordere Anteil entlang eines Innendurchmessers der axial flexiblen Schraubenfeder des ringförmig geschlossenen Typs und umgekehrt befindet.One previously unrecognized parameter, which has a lasting effect on the efficiency axially loaded springs of the annular closed type, is shown in U.S. Patent Nos. 4,826,144 and 4,915,366. These references disclose windings that interrelate in a manner are connected to a flexible coil spring of the annular closed Form type, wherein the rear portion along an outer diameter the axially flexible coil spring of the annular closed type and the front portion along an inner diameter of the axially flexible Coil spring of the annular closed type and vice versa.
Die gewählte Anordnung des hinteren Anschlagswinkels und des dadurch definierten hinteren Anteils eröffnet die Möglichkeit, eine axial flexible Schraubenfeder des ringförmig geschlossenen Typs „zuzuschneidern", die über das Spektrum der herkömmlichen, bereits bekannten flexiblen Schraubenfedern des ringförmig geschlossenen Typs hinausgeht.The elected Arrangement of the rear stop angle and defined thereby opened at the back the possibility, to "trim" an axially flexible coil spring of the annularly closed type, passing over the Spectrum of conventional, already known flexible coil springs of the annularly closed Type goes out.
Folglich können Federn mit höheren Last-Federwegs-Eigenschaften ausgestaltet werden. D.h., die Feder ist in der Lage, eine größere Kraft als Reaktion auf einen gegebenen Federweg auszuüben als eine Feder mit den gleichen Abmessungen und Drahtgrößen, deren hinterer Anteil entlang des Innendurchmessers der Feder verläuft.consequently can Springs with higher load-deflection characteristics be designed. That is, the spring is capable of greater force in response to a given travel as a spring with the same dimensions and wire sizes whose rear portion along the inner diameter of the spring extends.
Demzufolge können diese Federn aus kleineren Drähten hergestellt werden und einen engeren Wicklungsabstand aufweisen, während sie nach wie vor die gleiche Kraft als Reaktion auf einen Federweg wie Federn aus dem Stand der Technik ausüben können.As a result, can these springs are made of smaller wires produced and have a closer winding spacing, while they still use the same force in response to a spring travel Springs of the prior art can exercise.
Die vorliegende Erfindung betrifft die Ermittlung weiterer Parameter, die zur Konstruktion von Federn des ringförmig geschlossenen Typs mit ausgesuchten Last-Federwegs-Eigenschaften verwendet werden können.The The present invention relates to the determination of further parameters for the construction of springs of the annular closed type with selected load-travel characteristics can be used.
Gemäß der vorliegenden Erfindung weist eine Feder Betriebslast-Federwegs-Eigenschaften auf, die vorteilhafterweise zur Konstruktion von Federn mit bisher noch nicht möglichen Anwendungsbereichen eingesetzt werden können.According to the present Invention has a spring operating load-spring travel characteristics, which advantageously for the construction of springs with not yet possible Application areas can be used.
WO 99/49233 offenbart Torsionsschwingungsdämpfer, die Kraftspeicher umfassen, die als Druckminderungs-Schraubenfedern ausgelegt sein können. Die Kraftspeicher umfassen sich abwechselnde Federn mit geringeren Durchmessern und Federn mit größeren Durchmessern.WHERE 99/49233 discloses torsional vibration dampers comprising force accumulators, which may be designed as pressure-reducing coil springs. The Power accumulators include alternating springs with smaller diameters and springs with larger diameters.
